Cm, cramps, and nausea...

so i recently went through a miscarriage 5 weeks ago and my husband and i have decided to try again. i’ve attempted to track but i feel like it makes me more stressed and crazy. but over the past three days i have noticed little cramps in my lower abdomen. i’ve also had watery and clearly discharge. and it is as if now i’m getting more nauseous in the mornings.. could it be in my head or is this normal??
